*estimated from real time data

The first half of the week was quiet. During the second half
of the week a shock observed in the solar wind at 1006UT on 23 Jan. 
Active periods followed impulse. Shock originated from flare/CME
activity on 20 Jan. The region that produced this activity is 
located just past the centre of the solar disk at the time of writing of
this report. The region appears to be slightly declining, but 
still has M flare potential.

2. FORECAST (25 JANUARY - 25 FEBRUARY)
Disturbed Periods: 
Recurrence suggests mild activity possible on 31 Jan.

Best Quiet Periods: 
26-29 Jan
02-08 Feb


PEASE NOTE:  
At this time of the solar cycle, space weather conditions 
are frequently determined by short timescale events, not 
able to be forecasted a week in advance.
